Miniature rose plant named `Sweet Revenge`

ABSTRACT

The subject of the present disclosure is a new and distinct variety of miniature rose plant, named `Sweet Revenge` which is characterized by buds and blooms in shades of pale orange with a blush of deep orange on the outermost petals. Blooms of this rose are usually borne one to a stem with hybrid tea form and in sprays of 3 to 5 or more. The bush is vigorous, well-branched and produces moderate to heavy blooms.

The present invention relates to a new and distinct variety of a hardy, dwarf, bush plant of the miniature class; the variety being primarily characterized as orange blend.

The variety is further characterized by:

Long stemmed blooms of hybrid tea-type form, borne usually one to a stem and in compact sprays of 3 to 5 or more. The blooms are held very erect and well above the foliage.

The plant ranges in height from 24 to 36 inches (60 to 80 cm). The canes are sturdy and erect with moderate branching and medium to heavy foliage covering. The plant is a heavy bloomer that does well either in greenhouse or outdoors.

The plant has good growth habits, is well-shaped and attractive, bearing numerous leaflets of average size. Asexual reproduction of the new variety by cuttings derived from the plant stem, as performed at Chula Vista, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The seed parent was Tony Jacklin (hybridized by S. McGredy IV;introduced by McGredy; 1972), and the pollen parent was Pucker Up (U.S. Plant Pat. No. 5,407). It differs from its seed parent in the following ways. It is a miniature rose with open bloom size of 2 to 3 cm, and Tony Jacklin is a floribunda with open bloom size of 4 to 6 cm and an overall deep orange coloration. It differs from its pollen parent in the following ways. It produces blooms in shades of soft orange with a deep orange blush on the outermost petals, and Pucker Up produces blooms in orange-red over all petals.

The single color photographic view shows, in plain view, a bouquet of `Sweet Revenge` in various stages of maturity from bud stage to nearly open bloom stage.

The descriptive matter which follows pertains to roses grown and color values observed in plants and newly opened blooms in the months of March through November of 1995. The plants were grown outdoors in Chula Vista, Calif., and are believed to be accurate standards for this cultivar in similar conditions of soil and climate elsewhere.

Referring now specifically to the new and distinct variety of miniature rose plant names `Sweet Revenge`, the following is a detailed description thereof in outline; all major color plate identifications being by reference to the British Colour Council Horticultural Chart, except where common terms of color definition are employed.

Type: Hardy, dwarf, bushy, greenhouse or outdoor, exhibition or garden decorative potted plant.

Class: Miniature.

Variety name: Sweet Revenge.

Flowers borne: Usually one to a stem, but occasionally in sprays of 3 to 5 or more on erect stems with foliage well below the blooms.

Quantity of bloom: Heavy both outdoors or greenhouse grown.

Bud:

Peduncle.--Average length (30 to 50 mm); average diameter and sturdy; ranging from near Scheeles Green (860/3 to 806/1 page 176) with occasional tinting of bronze.

Hairs.--Extremely small and sparse with a reddish color; located over the surface of the peduncle and calyx tube.

Calyx.--Color range same as peduncle.

Opening.--Opens well in all weather.

Bloom:

Size when fully open.--Average for a miniature variety (40 to 50 mm).

Petalage.--Full -- 25 to 35 petals, arranged regularly, plus 5 to 10 petaloids.

Form.--Urn-shaped to ovoid as the bloom opens. The petals remain somewhat cupped with the apex and/or margins reflexed outward, becoming at maturity more loosely cupped.

Petals: Fairly thick with good substance; both the upper and under surfaces of all petals have a matte finish.

Shape.--Outer petals are of a broad obovate form. The intermediate petals are very much like the outer petals only narrower. The inner petals are a broad lanceolate form; and the petaloids are also lanceolate with some occasional irregularities.

Color: Newly opened flowers from plants grown outdoors (March through November of 1995), Chula Vista, Calif.:

Inner petals.--Upper and under surfaces -- Ranging from near Chinese Coral (614/2 to 614/1 page 614) to near Carrot red (612/3 to 612/2 page 612).

Outer petals.--Upper surfaces -- Ranging from near Chinese Coral (614/2 to 614/1 page 614) to near Carrot Red (612/2 to 612/1) at the base with a blush on the outer margins which ranges from near Carrot Red (612/1 to 612 page 612) to near Mars Orange (013/2 to 013/1 page 104). Note: Orange blush is deeper on blooms grown in warmer/sunny climates and paler on blooms grown in cooler climates or during overcast/cloudy days. Under surfaces -- Ranging from Near Chinese Coral (614/3 to 614/2 page 614) to near Carrot Red (612/3 to 612/2 page 612) with only occasional blush of near Carrot Red (612/2 to 612/1 page 612) on outermost petals.

General color effect.--Newly opened flowers -- Pale orange with a blush of deeper orange on margins of outermost petals. Three to five days open -- Orange blush deepens on the outermost petals. After five days -- Orange blush at darkest hue on outermost petals, while inner petals remain pale orange as bloom opens.

Flower longevity: (March through November 1995) Plant in pot 5 to 7 days from bud with sepals reflexed to fully open bloom. Holding at fully opened for 5 to 7 days longer. Cut blooms at living room temperature 10 to 14 days or longer.

Reproductive organs:

Stamens.--A generour amount arranged uniformly around the pistil.

Filaments.--Varying in length with shorter filaments more proximal to the pistil; pale yellow in color with anthers of golden yellow.

Pollen.--Abundant.

Pistil.--Short, spreading and abundant; pale yellow.

Ovaries.--All encased in calyx.

Hips.--Some.

Seeds.--3 to 5 or more in each hip.

Foliage:

Sepals.--Permanent; simple and glabrous; spear-shaped; open as the bloom opens, recurving against the peduncle, when the bloom is fully opened. Occasional foliaceous appendages attractively supplement sepal terminals; these are of varying lengths.

Leaves.--5 to 7 leaflets on average; medium size for a miniature rose plant.

Leaflets.--Broad ovate-shaped.

Margins.--Very serrated with tinting of bronze, especially noticeable on the newer foliage.

Upper surfaces have a semi-glossy finish, and the under surfaces have a matte finish of a slightly lighter shade than the upper surfaces.

Rachis.--Medium strength; upper surface is grooved with very small hairs over the length of it. Under surface has few if any hairs but does contain 2 to 5 small thorns.

Stipules.--Varying in length from small to medium; average width; tapering auricles angled outward at about 45 degrees.

Growth:

Habit.--Dwarf, bush; above average for a miniature rose plant.

Rate and character.--Vigorous and well-branched.

Canes.--Medium diameter; sturdy; held erect.

Main stems.--Color range same as foliage.

Thorns.--Average less than 5 to 10 per 10 cm on the main stems and branches. Reddish in color; average size; slender and hooked slightly downward.

Branches.--Coloration ranges the same as does that of the foliage.

The miniature rose plant and its flowers as herein described may vary in slight detail due to climate, soil and cultural conditions under which the variety may be grown; the present description being of the variety as grown in Chula Vista, Calif.

No information related to insect, disease or frost tolerance is available due to the controlled growing conditions under which our plants are produced and maintain, which includes regular application of fungicides and pesticides on all plants and the immediate elimination of any inferior seedlings which demonstrate a tendency to develop diseases or other unpleasant habits. As to frost tolerance, all of our plants are grown in Chula Vista, Calif. which is located in a moderate temperature zone that would rarely experience frost or freezing temperatures. For the above mentioned reasons, the specifications have not been expanded further.
